For decades, venture capital firms largely avoided sectors like defense, energy, manufacturing and heavy industry, deeming them too complex, too heavily regulated, and too slow to generate the rapid returns favored by the VC model. But a significant shift is underway. Investors are increasingly pouring capital into these “hard” sectors, driven by geopolitical pressures, technological advancements, and a reassessment of long-term value. This change signals a fundamental recalibration of what’s considered investable, potentially unlocking a modern wave of innovation in foundational industries.
The perception of these industries as unviable for venture backing stemmed from lengthy procurement cycles, stringent regulations, and the dominance of established players. However, recent trends suggest Here’s changing. Government technology spending more than doubled between 2021 and 2025, and investment in defense technology more than doubled in 2025 alone, indicating a growing appetite for innovation in these areas. This influx of capital is fueled by a recognition that these sectors are ripe for disruption, particularly with the advent of new technologies.
The Rise of AI and the Changing Investment Landscape
Artificial intelligence is arguably the biggest catalyst for this shift. By lowering the cost of building sophisticated software and accelerating development cycles, AI allows startups to compete with incumbents in sectors previously considered impenetrable. As software becomes more easily replicated, competitive advantage is shifting towards operational expertise, user experience, and seamless integration with existing systems. This is particularly true in industries like construction, mining, and logistics, where AI-powered solutions can deliver immediate performance gains.
Historically, the barriers to entry in these sectors were substantial. Public procurement processes can take years, constrained by budgetary cycles and regulatory frameworks. Energy projects face complex permitting structures, and infrastructure deployments require extensive certification. However, these very challenges are now being viewed as potential advantages. Regulation, once seen as a deterrent, is increasingly understood as a “moat,” protecting startups that successfully navigate the compliance landscape from new entrants.
Macroeconomic Factors and Geopolitical Pressures
Beyond technological advancements, broader macroeconomic and geopolitical forces are driving investment into these sectors. Supply chain disruptions, energy insecurity, and infrastructure fragility have elevated industrial resilience to a national priority. Governments are investing heavily in grid modernization, logistics networks, and critical infrastructure, creating a structurally supportive environment for startups offering innovative solutions. This is coupled with increasing pressure on public institutions to digitize procurement, compliance, and workflow systems, further expanding the market opportunity.
The saturation of the horizontal SaaS market is likewise playing a role. Investors, seeking differentiated returns, are looking beyond crowded software categories threatened by the rapid innovation of companies like OpenAI and Anthropic. Regulated and infrastructure-heavy sectors offer less competition, stronger pricing power, and significantly larger total addressable markets (TAMs). Companies like SAP, Caterpillar, and Siemens, with market capitalizations in the billions, demonstrate the potential scale of these opportunities.
Founders with Domain Expertise Lead the Charge
A key factor in this shift is the emergence of founders with deep industry expertise. Many startups in defense, energy, healthcare, and government procurement are led by individuals who come directly from these sectors, possessing unique insights into their challenges and opportunities. Unlike legacy players burdened by established workflows and organizational inertia, these founders are able to innovate with speed and agility.
Even established companies are recognizing the need to adapt. Salesforce, for example, is increasingly relying on acquisitions to stay competitive, highlighting the difficulty for incumbents to preserve pace with the rapid innovation occurring in these sectors. This demonstrates that the cost of switching away from legacy solutions is decreasing, making it easier for startups to gain market share.
As investor playbooks evolve, we can expect to see more $100 billion companies emerge from this cycle. The focus is no longer solely on building better software, but on rebuilding the foundational sectors of the global economy. This represents a significant opportunity for startups to disrupt established industries and drive innovation on a massive scale.
The coming years will likely see continued investment in these traditionally “uninvestable” sectors, as investors recognize the potential for both financial returns and positive societal impact. The convergence of AI, geopolitical pressures, and a new generation of industry-focused founders is creating a fertile ground for innovation and disruption.
